Development Background
Scale is always essential in fresh food area in both traditional supermarkets and new retail markets. However, the increasing labour cost leaves more and more weighing areas unattended zones, where cutomers need to weigh and print receipts by themselves. Accordingly, SUNMI releases this all-in-one intelligent scale, S2, with the functions of weighing, checkout and receipt printing. Its 15.6" extra large touch screen with the simple&user-friendly HMI makes S2 an easy-to-use scale as well as brings enhanced user experience.
  • Much space occupied, messy counter, dull look.
  • Low labor efficiency, high consumables cost.
  • Poor compatibility, high failure risk.
  • Increasing operating cost.
Advanced technology for faster and stronger performance.
Users are always surprised by the smooth operation of SUNMI S2 when they choose this intelligent cashier scale. S2's quality is also guranteed by a cutting-edge processor and SUNMI OS, which makes S2 always smooth like a new one.
  • High Performance Octa-Core Processor.
    Mobile processor leading brand.
    High performance, low power consumption, full connectivity.
  • Android 7.1
    Promoted safety & stability.
    Increase the software running speed.
  • SUNMI OS 2.3
    Over 50 items have been developed and optimized based on the feedback from users of previous OS.
eSIM is coming,
starting a no card new era.
S2 is an intelligent cashier scale with eSIM card, which saves you from installing any SIM card. You can feel free to choose operators and use relevant services. It avoids the risk brought by SIM card loss and allows users to remotely delete all the data for security reasons even if the whole device is lost.

Slim Prop With Great Style
Stable and fashionable.
  • Light & thin and high-end stand column design.
    The whole surface of the stand column is covered by two parts: metallic titanium and black, which produces the great style & slim visual effect.
    Orange embellishments on both sides, which break the boring atmosphere, and combine being steady with fashion.
    The printer cover is independent of the surface of stand column, which creates the sense of volume sufficiently & obviously.
  • Built-in Seiko 80mm printer.
    No externally connected printer needed.
    Immediate receipt printing after payment.
  • Higher capacity of paper bin
    Longer print time limit
    The whole surface of the stand column is covered by two parts: metallic titanium and black, which produces the great style & slim visual effect.
    Orange embellishments on both sides, which break the boring atmosphere, and combine being steady with fashion.
    The printer cover is independent of the surface of stand column, which creates the sense of volume sufficiently & obviously.
  • New print technology
    To promote efficiency
    In cooperation with senior Seiko experts, SUNMI has upgraded & built with them together 80 mm thermal printer with a brand new generation of “Print Technology” in terms of individual paper jam phenomena.
    Thus, the amount of paper jam phenomena is reduced and the printing has become more natural & smooth, saving both worry & time.
    The fastest printing speed of 200 mm/s, which is suitable for any usage scenarios, more than sufficient even when queuing for number take during the rush hour.
    The high quality that Seiko adheres to has accomplished a print life of up to 150 km, and this printer does not need additional maintenance in normal usage in all conditions.
Suspended Aluminum Alloy Die-Casted Scale Body Design
Highlight the sense of science and technology | Improve the user experience
  • Design of aluminum alloy die-casted scale body
    The gap between the scale pan and the base is highlighted by orange ribbon to improve visual experience.
    It is light & thin, with scale pan upward on both sides, to increase sense of suspension and highlight the sense of science & technology.
    Meanwhile, there is certain limit to the commodity that needs to be weighed to prevent rolling down.
  • Design of adjustable stand bar.
    Expose the stand bar by cutting open four corners at the bottom of the weighing platform along the diagonal line.
    for ease of installation and adjusting the levelling of the weighing platform, and also for more light & handy base.
    The easily adjustable stand bar has increased the efficiency of installation.
  • Design of closed base.
    Completely closed base design| anti-corrosion |dirt resistant | antifouling | mothproof | Long survival
    under worse environment no matter in fresh food supermarket or fruits franchise store.
  • Professional sensors equipped with
    advanced algorithms | Higher scale accuracy | Higher quality
    Specialized high precision AD conversion chip of TI - internationally famous brand Temperature compensation technology to ensure the outstanding performance of the sensor from severe winter to hot summer Digital sensor algorithm
    Highly integrated into AD board module
    Easy maintenance
